CROSS-REFERENCE TO RELATED APPLICATIONS

The present application is based on, and claims priority from, Chinese application number 202210820737.2, filed Jul. 13, 2022, the disclosure of which is hereby incorporated by reference herein in its entirety.

TECHNICAL FIELD

Embodiments of the present disclosure relate to the field of computer technology, and in particular, to a document content point-and-select method, electronic apparatus and medium.

BACKGROUND

Untagged documents, such as PDF files, can be easier to read and display the page with the same effect on different devices. At present, the interface interaction for untagged documents is usually to: click and pull back to select.

However, the inventor found that when using the above method to perform interface interaction in an untagged document, there are often the following technical problems:

First, the user needs to accurately pull and select the document content which needs to be selected. When the pulled and selected document content is incorrect, the user needs to do it again, which makes the user's operation rather cumbersome, and when pulls to the end of the document content to be selected, in order to accurately select the document content, the user needs to slow down the pull speed, which results in a fairly long time for pulling and selecting the document content.

Second, it is impossible to automatically select an entire sentence, which makes it impossible to quickly perform operations related to the entire sentence, and thus cannot quickly translate the entire sentence.

Third, copy and paste can only be performed based on the characters in the table displayed in the untagged document, and the complete table cannot be automatically copied.

The above information disclosed in this background section is only for enhancement of understanding of the background of the inventive concept and therefore it may contain information that does not form the prior art that is already known in this country to a person having ordinary skill in the art.

SUMMARY

Some embodiments of the present disclosure propose a document content point-and-select method, electronic apparatus and computer-readable medium to solve one or more of the technical problems mentioned in the above background section.

In the first aspect, some embodiments of the present disclosure provide a document content point-and-select method for an untagged document, the method comprising: in response to detecting a point-and-click operation acting on the untagged document, determining the document location information of the point-and-click operation; determining a document structure recognition result of the document content at the document location characterized by the document location information in the untagged document; in response to determining that the point-and-click operation is a first point-and-click operation, selecting the word text corresponding to the document location information from the document structure recognition result as a target word, and highlighting the area corresponding to the target word in the untagged document; in response to determining that the point-and-click operation is a second point-and-click operation, selecting the sentence text corresponding to the document location information from the document structure recognition result as a target sentence, and highlighting the area corresponding to the target sentence in the untagged document.

In the second aspect, some embodiments of the present disclosure provide a document content point-and-select device for an untagged document, the device comprising: a first determination unit, configured to determine, in response to detecting a point-and-click operation acting on the untagged document, the document location information of the point-and-click operation; a second determination unit, configured to determine a document structure recognition result of the document content at the document location characterized by the document location information in the untagged document; a first display unit, configured to select the word text corresponding to the document location information from the document structure recognition result as a target word, and highlight the area corresponding to the target word in the untagged document, in response to determining that the point-and-click operation is a first point-and-click operation; a second display unit, configured to select the sentence text corresponding to the document location information from the document structure recognition result as a target sentence, and highlight the area corresponding to the target sentence in the untagged document, in response to determining that the point-and-click operation is a second point-and-click operation.

In the third aspect, some embodiments of the present disclosure provide an electronic apparatus, comprising: one or more processors; a storage device on which one or more programs are stored, and when the one or more programs are executed by the one or more processors, the one or more processors are made to implement the method described in any of the implementations in the first aspect above.

In the fifth aspect, some embodiments of the present disclosure provide a computer program product, comprising a computer program which, when executed by a processor, implements the method described in any of the implementations in the first aspect above.

The above embodiments of the present disclosure have the following beneficial effects: through the document content point-and-click method of some embodiments of the present disclosure, the user operation of selecting the document content in an untagged document is simplified, and the time for the user to select the document content in an untagged document is shortened. To be specific, the reason why the user's operation of selecting the document content in an untagged document is cumbersome and the time for the user to select the document content in an untagged document is rather long is that: the user needs to accurately pull and select the document content which needs to be selected, and if the pulled and selected document content is incorrect, the user needs to do it again, which makes the user's operation rather cumbersome, and when pulls to the end of the document content to be selected, in order to accurately select the document content, the user needs to slow down the pull speed, which results in a fairly long time for pulling and selecting the document content. On this basis, the document content point-and-select method according to some embodiments of the present disclosure, in response to detecting a point-and-click operation acting on the untagged document, first determines the document location information of the point-and-click operation. Thus, the document location information can characterize the location where the user clicked in the untagged document. Then, a document structure recognition result of the document content at the document location characterized by the document location information in the untagged document is determined. Thus, through the location clicked by the user in the untagged document, the document structure recognition result of the document content corresponding to the location can be determined. Thereafter, in response to determining that the point-and-click operation is a first point-and-click operation, select the word text corresponding to the document location information from the document structure recognition result as a target word, and highlight the area corresponding to the target word in the untagged document. Therefore, when the point-and-click operation is a first point-and-click operation, select and highlight the word text corresponding to the clicked location from the document structure recognition result, thus showing the effect of having selected a word. Finally, in response to determining that the point-and-click operation is a second point-and-click operation, select the sentence text corresponding to the document location information from the document structure recognition result as a target sentence, and highlight the area corresponding to the target sentence in the untagged document. Therefore, when the point-and-click operation is a second point-and-click operation, select and highlight the sentence text corresponding to the clicked location from the document structure recognition result, thus showing the effect of having selected a sentence. Also because the user does not use the pull-and-select method when making selections, the content in the untagged document can be selected directly through a point-and-click operation, thus simplifying the user's operation of selecting the document content in an untagged document and shortening the time for the user to select the document content in an untagged document.

FIG. 1 shows a flow 100 of some embodiments of a document content point-and-select method according to the present disclosure. The document content point-and-select method comprises the following steps of:

Step 101, in response to detecting a point-and-click operation acting on an untagged document, determining the document location information of the point-and-click operation.

In some embodiments, the execution body (e.g., a computing device) of the document content point-and-select method may, in response to detecting a point-and-click operation acting on an untagged document, determine the document location information of the point-and-click operation. Wherein, the untagged document may be a document with no structured label to identify the document structure. For example, the untagged document may be, but not limited to, a PDF (Portable Document Format) document. The document location information may be information characterizing the location of the point-and-click operation in the untagged document. The document location information may include document coordinates. The document coordinates may characterize the location in the document, and may include abscissa and ordinate. For example, document coordinates can be PDF coordinates. In practice, the execution body may determine the document coordinates at the location corresponding to the point-and-click operation as the document location information.

It should be noted that the above computing device may be hardware or software. When the computing device is hardware, it can be implemented as a distributed cluster composed of multiple servers or terminal devices, or can be implemented as a single server or a single terminal device. When the computing device is embodied as software, it may be installed in the hardware devices listed above. It can be implemented, for example, as multiple software or software modules for providing distributed services, or as single software or software module. No specific limitation is made here.

It should be understood that the number of computing devices is merely illustrative. There may be any number of computing devices depending on implementation needs.

Step 102, determining a document structure recognition result of the document content at the document location characterized by the document location information in the untagged document.

In some embodiments, the execution object may determine a document structure recognition result of the document content at the document location characterized by the document location information in the untagged document. Wherein, the document structure recognition result may be a recognition result obtained after performing document structure recognition on the document content. The document structure recognition result may include text content. The document structure recognition result may also include, but is not limited to, text types. The text content may include the recognized text. The text types can be the types of document content. For example, the text types may include, but are not limited to: headings, paragraphs, charts, images, tables. In practice, the execution body may determine whether there are respective document structure recognition results corresponding to the current document page. Then, in response to determining that there are not respective document structure recognition results corresponding to the current document page, recognize the document structure of the current document page to obtain respective document structure recognition results. For example, document structure recognition can be performed by means of object detection. Secondly, in response to determining that there are respective document structure recognition results corresponding to the current document page, select, from the respective document structure recognition results, a document structure recognition result that the document region of the corresponding document content contains the document coordinates included in the document location information may. Finally, the selected document structure recognition result may be determined as the document structure recognition result of the document content at the document location characterized by the document location information.

Alternatively, before step 101, the execution body may perform a document structure recognition processing on the untagged document to obtain a document structure recognition result set.

In certain optional implementations of some embodiments, the execution body may determine, from the document structure recognition result set, a document structure recognition result of the document content at the document location characterized by the document location information in the untagged document. In this way, the document structure recognition can be performed on the entire untagged document in advance, such that a document structure recognition result at the current click location can be selected from the document structure recognition result set recognized in advance.

Step 103, in response to determining that the point-and-click operation is a first point-and-click operation, selecting the word text corresponding to the document location information from the document structure recognition result as a target word, and highlighting the area corresponding to the target word in the untagged document.

In some embodiments, the execution body may, in response to determining that the point-and-click operation is a first point-and-click operation, select the word text corresponding to the document location information from the document structure recognition result as a target word, and highlight the area corresponding to the target word in the untagged document. Wherein, the first point-and-click operation may be an operation for clicking on a word. For example, the first point-and-click operation may be a double-click operation. Here, the specific setting of the first point-and-click operation is not limited. The first point-and-click operation may be, but is not limited to, one of the following: a single-click operation, a double-click operation, a triple-click operation, and a shortcut-key click-combination operation. The shortcut-key click-combination operation may be N point-and-click operations performed after pressing at least one shortcut key. The area corresponding to the target word may be an area of the bounding box of the target word in the untagged document. The bounding box may be a smallest bounding box, or be a bounding box whose length is greater than or equal to the length of the smallest bounding box of the target word and/or whose width is greater than or equal to the width of the smallest bounding box of the target word. In practice, first, the execution body can select the word text corresponding to the document location information from the document structure recognition result as the target word by the following steps to:

In the first step, select from the document structure recognition result a character text whose corresponding character location information and the document location information satisfy a first preset distance condition, as a target character text. Wherein, the character location information may be information characterizing the location of a single character. For example, the character position information can characterize the central coordinate position of a single character. For another example, the character location information can also characterize the vertex coordinate positions of the smallest bounding box of a single character. The character location information may be expressed in document coordinates. The above character text may be characters in the text content included in the document structure recognition result. The first preset distance condition may be “the distance between the document coordinates of the character text and the document coordinates included in the document location information is the smallest”.

In the second step, select from the document structure recognition result a first preset number of character texts arranged before the target character text, as an anterior character text, and obtain an anterior character text sequence. Wherein, the first preset number may be a number set in advance. Here, the specific setting of the first preset number is not limited. For example, the first preset number may be 10.

In the third step, select from the document structure recognition result a second preset number of character texts arranged behind the target character text, as a posterior character text, and obtain a posterior character text sequence. Wherein, the second preset number may be a number set in advance. Here, the specific setting of the second preset number is not limited. For example, the second preset number may be 10. It should be noted that the second preset number may be the same as the first preset number, or may be different from the first preset number.

In the fourth step, combine the anterior character text sequence and the posterior character text sequence successively to obtain a combined text. In practice, the above execution body may splice the posterior character text sequence after the anterior character text sequence to obtain a combined text.

In the fifth step, perform word segmentation processing on the combined text to obtain a word segmentation text set. In practice, the above execution body may use a word segmentation algorithm to perform word segmentation processing on the combined text to obtain the word segmentation text set. For example, the word segmentation algorithm may be a mechanical word segmentation algorithm, a word segmentation algorithm based on a hidden Markov model, or a word segmentation algorithm based on a conditional random field.

In the sixth step, select from the word segmentation text set a word segmentation text whose corresponding word location information and the document location information satisfy a second preset distance condition, as the word text corresponding to the document location information, so as to use the word text as a target word. Wherein, the word location information may be information characterizing the location of the word text. For example, the word location information can characterize the central coordinate position of the word text. For another example, the word location information can also characterize the vertex coordinate positions of the smallest bounding box of the word text. The word location information may be expressed in document coordinates. The second preset distance condition may be “the distance between the document coordinates of the word text and the document coordinates included in the document location information is the smallest”.

Then, the smallest bounding box of the target word can be displayed in the untagged document, so that the target word is highlighted.

Step 104, in response to determining that the point-and-click operation is a second point-and-click operation, selecting the sentence text corresponding to the document location information, from the document structure recognition result, as a target sentence, and highlighting the area corresponding to the target sentence in the untagged document.

In some embodiments, the execution body may, in response to determining that the point-and-click operation is a second point-and-click operation, select the sentence text corresponding to the document location information, from the document structure recognition result, as a target sentence, and highlight the area corresponding to the target sentence, in the untagged document. Wherein, the second point-and-click operation may be an operation for clicking on a single sentence. For example, the second point-and-click operation may be a shortcut-key click-combination operation. For example, the shortcut-key click-combination operation may be one point-and-click operation performed after pressing the “Alt” key. Here, the specific setting of the second point-and-click operation is not limited. The second point-and-click operation may be, but not limited to, one of the following: a single-click operation, a double-click operation, a triple-click operation, and a shortcut-key click-combination operation. The area corresponding to the target sentence may be an area of the bounding box of the target sentence in the untagged document. The bounding box may be a smallest bounding box, or a bounding box whose length is greater than or equal to the length of the smallest bounding box of the target sentence and/or whose width is greater than or equal to the width of the smallest bounding box of the target sentence. In practice, firstly, the execution body can select the sentence text corresponding to the document location information, from the document structure recognition result, as the target sentence by the following steps to:

In the first step, select from the document structure recognition result a character text whose corresponding character location information and the document location information satisfies a first preset distance condition, as a target character text.

In the second step, determine the character text in the document structure recognition result, that satisfies a preset sentence start location condition corresponding to the target character text, as a sentence start character. Wherein, the preset sentence start location condition may be “the sentence-ending character before the character text is a sentence-ending character which is before the target character text and is closest to the target character text”. A sentence-ending character can be a character that characterizes the end of a sentence. For example, it can be the character “○” or the character “.”.

In the third step, determine the sentence-ending character that satisfies a preset sentence end location condition corresponding to the target character text in the document structure recognition result, as a sentence end character. Wherein, the preset sentence end location condition may be “the sentence-ending character is a sentence-ending character which is behind the target character text and is closest to the target character text”.

In the fourth step, determine the text from the sentence start character to the sentence end character in the document structure recognition result, as a sentence text corresponding to the document location information, so as to use the sentence text as a target sentence.

Then, display the smallest bounding box of the target sentence in the untagged document, so as to highlight the target sentence.

Alternatively, the above execution body may highlight the area corresponding to the target sentence in the untagged document through the following steps to:

In the first step, superimpose the display of a highlight layer for the area corresponding to the target sentence in the untagged document according to a preset transparency, preset fill color and preset border information. Wherein, the preset transparency may be a transparency set in advance. For example, the preset transparency may be 20%. The preset fill color may be a preset color for filling the highlight layer. The preset fill colors can be represented by color numbers. The preset boarder information may be boarder-related information of the preset highlight layer. The preset border information may include border color, border style information, and border thickness. The border style information may be information related to the border style, and may include a style identification number characterizing the border style. The highlight layer may be a floating layer for superimposing the area corresponding to the target sentence for display. Here, the size of the highlight layer may be the same as the smallest bounding box of the target sentence, or may be larger than the smallest bounding box of the target sentence. Thus, the area corresponding to the target sentence can be displayed in a selected effect, according to the preset transparency, preset fill color and preset border information.

In the second step, display a sentence editing toolbar at the preset position of the highlight layer. Wherein, the preset position may be above or below the highlight layer. Here, the specific setting of the preset position is not limited. The above sentence editing toolbar may be a toolbar for editing the sentence text. In the sentence editing toolbar display a sentence translation control, at least one sentence annotation control, sentence erasing control, and sentence copy control. The sentence translation control may be a control for receiving a selection operation to translate the target sentence. Here, the translation method can be English-Chinese translation by default, or can be set by the user themselves. The sentence annotation control in the above at least one sentence annotation control may be a control for performing annotation processing on the target sentence. The at least one sentence annotation control may include, but is not limited to, at least one of the following: an underline annotation control, a delete annotation control, and a highlight annotation control. The sentence erasing control may be a control for erasing the target sentence. The sentence copy control may be a control for copying the target sentence.

In the third step, in response to detecting a selection operation acting on the sentence translation control, display a translated text corresponding to the target sentence and a translated text copy control corresponding to the translated text. In practice, the execution body may display the translated text corresponding to the target sentence above or below the highlight layer. The translated text copy control corresponding to the translated text may be displayed below the translated text.

In the fourth step, in response to detecting the selection operation acting on the translated text copy control, copy the translated text for pasting the translated text.

In the fifth step, in response to detecting the selection operation acting on the sentence erasing control, display the target sentence displayed in the untagged document to be the background color of the untagged document. Thus, displaying the background color of the untagged document can achieve the effect of erasing the target sentence.

In the sixth step, in response to detecting the selection operation acting on the sentence copy control, copy the target sentence for pasting the target sentence. Here, the selection operation may include, but is not limited to, at least one of the following: clicking, dragging, and hovering.

In the seventh step, in response to detecting the selection operation acting on any sentence annotation control in the at least one sentence annotation control, and according to the annotation mode corresponding to any sentence annotation control, annotate the target sentence displayed in the untagged document. For example, if the user can click on the underline annotation control, an underline will be displayed below the target sentence displayed in the untagged document.

Alternatively, the execution body can also, in response to detecting that the point-and-click operation is a sixth point-and-click operation, select the sentence text corresponding to the document location information, from the document structure recognition result, as a target sentence, and highlight the area corresponding to the target sentence in the untagged document, and display the translated text corresponding to the target sentence. Wherein, the sixth point-and-click operation may be an operation for directly translating a single sentence after clicking on the single sentence. For example, the sixth point-and-click operation may be a shortcut-key click-combination operation. For example, the sixth point-and-click operation may be one point-and-click operation performed after pressing the “Alt” and “Ctrl” keys. Here, the specific setting of the sixth point-and-click operation is not limited. The sixth point-and-click operation may be, but not limited to, one of the following: a single-click operation, a double-click operation, a triple-click operation, and a shortcut-key click-combination operation. In practice, the execution body may display a floating window at the surrounding position of the target sentence in the untagged document. Wherein, the translated text corresponding to the target sentence is displayed in the floating window. The surrounding position may be a position in any direction displayed corresponding to the target sentence. For example, the surrounding position may be above or below the target sentence. Thus, the user can be further enabled to quickly translate the entire sentence.

The above technical solution, as an inventive point of the embodiments of the present disclosure, solves the second technical problem mentioned in the background art: it is impossible to automatically select an entire sentence, which makes it impossible to quickly perform operations related to the entire sentence, and thus cannot quickly translate the entire sentence. The factor that makes it impossible to quickly translate the entire sentence is often as follows: it is impossible to automatically select an entire sentence, which makes it impossible to quickly perform operations related to the entire sentence. If the above factor is solved, the effect of fast translation of the entire sentence can be achieved. In order to achieve this effect, the present disclosure displays a sentence editing toolbar when highlighting the area of the target sentence. In the sentence editing toolbar display a sentence translation control, at least one sentence annotation control, sentence erasing control, and sentence copy control, so the user can quickly perform related operations on the entire sentence through various controls in the sentence editing toolbar. Also because the sentence translation control is displayed in the sentence editing toolbar, the entire sentence can be quickly translated.

Alternatively, the execution body may, in response to determining that the point-and-click operation is a third point-and-click operation, select a paragraph text corresponding to the document location information, from the document structure recognition result, as a target paragraph, and highlight the area corresponding to the target segment in the untagged document. Wherein, the third point-and-click operation may be an operation for clicking on a single paragraph. For example, the third point-and-click operation may be a triple-click operation. Here, the specific setting of the third point-and-click operation is not limited. The third point-and-click operation may be, but not limited to, one of the following: a single-click operation, a double-click operation, a triple-click operation, and a shortcut-key click-combination operation. The area corresponding to the target segment may be an area of the bounding box of the target segment in the untagged document. The bounding box may be a smallest bounding box, or a bounding box whose length is greater than or equal to the length of the smallest bounding box of the target paragraph and/or whose width is greater than or equal to the width of the smallest bounding box of the target paragraph. In practice, the execution body may, in response to determining that the text type included in the document identification result is a paragraph, determine the text content included in the document identification result to be the paragraph text corresponding to the document location information, as the target paragraph. Then, the smallest bounding box of the target paragraph can be displayed in the untagged document, so that the target paragraph can be highlighted. Thus, the user can quickly select the paragraph text in the untagged document.

Alternatively, firstly, the execution subject may, in response to determining that the point-and-click operation is a fourth point-and-click operation, determine whether there is a table corresponding to the document location information in the document structure recognition result. Wherein, the fourth point-and-click operation may be an operation for clicking on a table. For example, the fourth point-and-click operation may be a triple-click operation. Here, the specific setting of the fourth point-and-click operation is not limited. The fourth point-and-click operation may be, but not limited to, one of the following: a single-click operation, a double-click operation, a triple-click operation, and a shortcut-key click-combination operation. In practice, the execution body may determine that a table corresponding to the document location information exists in the document structure recognition result, in response to determining that the text type included in the document recognition result is a table. Then, in response to determining that there is a table corresponding to the document location information in the document structure recognition result, use the table as a target table, and highlight the area corresponding to the target table in the untagged document. Wherein, the area corresponding to the target table may be an area of the bounding box of the target table in the untagged document. The bounding box may be a smallest bounding box, or a bounding box whose length is greater than or equal to the length of the smallest bounding box of the target table and/or whose width is greater than or equal to the width of the smallest bounding box of the target table. In practice, the smallest bounding box of the target table may be displayed in the untagged document, so as to highlight the target table. Thus, the user can quickly select the entire table in the untagged document.

Alternatively, the execution body may highlight the area corresponding to the target table in the untagged document by the following steps to:

In the first step, display a bounding box outside the area corresponding to the above target table in the untagged document, for highlighting. The size of the bounding box may be larger than the size of the smallest bounding box of the target table. In practice, the execution body may display the bounding box outside the area corresponding to the target table in the untagged document, according to a preset color for displaying the bounding box.

In the second step, at a preset page position where the page of the untagged document is displayed, display a table corresponding to the document location information in the document structure recognition result and a table editing toolbar corresponding to the table. Wherein, the preset page position may be a position set in advance in the page. For example, the preset page position may be the sidebar position on the right side of the untagged document in the above page. The table corresponding to the document location information may be a structured table obtained through document structure recognition. The table displayed at the preset page position may have a border. The table editing toolbar may be a toolbar for editing the table displayed at the preset page position. A table copy control and at least one table adjustment control are displayed in the table editing toolbar. The table copy control may be a control for copying the table displayed at the preset page position. The table adjustment control in the above at least one table adjustment control may be a control for adjusting a table. The at least one table adjustment control may include, but is not limited to, at least one of the following: a table border adjustment control group, a border style adjustment control group, and an alignment mode adjustment control group.

In the third step, in response to detecting an adjustment operation acting on any table adjustment control in the at least one table adjustment control, update the display of the table displayed at the preset page position according to the adjustment operation. Wherein, the adjustment operation may be an operation of adjusting the table. For example, the adjustment operation may be a selection operation acting on the table border adjustment controls in the above table border adjustment control group. As an example, the user firstly selects all the tables displayed at the preset page positions, then selects the corresponding center-aligned alignment mode adjustment control in the alignment mode adjustment control group. Then, the alignment mode of the characters in the table displayed at the preset page position is updated to the center alignment. Thereby, the identified structured tables can be adjusted.

In the fourth step, in response to detecting a selection operation acting on the table copy control, copy the table displayed at the preset page position, for table pasting. In this way, the table displayed at the preset page position can be copied.

The above technical solution, as an inventive point of the embodiments of the present disclosure, solves the technical problem 3 mentioned in the background art: “copy and paste can only be performed based on the characters in the table displayed in the untagged document, and the complete table cannot be automatically copied”. In order to achieve the effect of automatically copying the complete table, the present disclosure, when highlighting an area of the target table, displays, at a preset page position where the page of the untagged document is displayed, a table corresponding to the document location information in the document structure recognition result and a table editing toolbar corresponding to the table. A table copy control and at least one table adjustment control are displayed in the table editing tool bar, so that the user can adjust the table displayed at the preset page position through the table adjustment control. The table displayed in the preset page position can be copied through the table copy control. Also because the table displayed at the preset page position is a structured table obtained through document structure recognition and has a border, the complete table can be automatically copied through the table copy control.

Alternatively, first, the above execution body may, in response to determining that the point-and-click operation is a seventh point-and-click operation and that the document structure recognition result has a table corresponding to the document location information, select the text of a cell corresponding to the document location information from the above table as a cell text. The above seventh point-and-click operation may be an operation for clicking on the cell text in the table. For example, the seventh point-and-click operation may be a double-click operation in the table area. Here, the specific setting of the seventh point-and-click operation is not limited. The seventh point-and-click operation may be, but not limited to, one of the following: a single-click operation, a double-click operation, a triple-click operation, and a shortcut-key click-combination operation. Then, the area corresponding to the cell text in the untagged document may be highlighted. Wherein, the area of the cell text may be a bounding box of the cell text. The bounding box may be a smallest bounding box, or a bounding box whose length is greater than or equal to the length of the smallest bounding box of the cell text and/or whose width is greater than or equal to the width of the smallest bounding box of the cell text. The area of the cell text may also be a cell of the cell text. In practice, the execution body may highlight the area of the cell text. Thus, the user can quickly select the cell text in the table.

Alternatively, the above execution body may also display a cell editing toolbar at a position outside the preset cell in the area corresponding to the cell text. Wherein, the position outside the preset cell may be any position around the cell. For example, the position outside the preset cell may be below the cell. The cell editing toolbar may be a toolbar for editing the cell text and/or the cell of the cell text. In the cell editing toolbar, a cell text copy control, at least one cell text annotation control, and at least one cell annotation control may be displayed. The cell text copy control may be a control for receiving a user's selection operation to copy the cell text. The cell text style annotation control may be a control for annotating the text style of the cell text. For example, the at least one cell text style annotation control may include a cell text annotation control characterizing a deletion of the cell text. The cell annotation control may be a control for annotating the cell of the cell text. For example, the at least one cell annotation control may include a cell annotation control for highlighted annotation of the cells. The execution body may, in response to detecting a selection operation acting on the cell text copy control, copy the cell text, for pasting the cell text. Thus, the user can perform related operations on the selected cell text or cell, through the controls displayed in the cell editing toolbar.

Alternatively, firstly, the execution body may, in response to determining that the point-and-click operation is a fifth point-and-click operation, determine whether there is a graph corresponding to the document location information in the document structure recognition result. Wherein, the fifth point-and-click operation may be an operation for clicking on a chart or an image. For example, the fifth point-and-click operation may be a single-click operation. Here, the specific setting of the fifth point-and-click operation is not limited. The fifth point-and-click operation may be, but not limited to, one of the following: a single-click operation, a double-click operation, a triple-click operation, and a shortcut-key click-combination operation. In practice, the execution body may, in response to determining that the text type included in the document recognition result is a chart or an image, determine that there is a graph corresponding to the document location information in the document structure recognition result. Then, in response to determining that there is a graph corresponding to the document location information in the document structure recognition result, use the graph as a target graph, and highlight the area corresponding to the target graph in the untagged document. Wherein, the above graph may be a chart or an image. The area corresponding to the target graph may be an area of the bounding box of the target graph in the untagged document. The bounding box may be a smallest bounding box, or a bounding box whose length is greater than or equal to the length of the smallest bounding box of the target graph and/or whose width is greater than or equal to the width of the smallest bounding box of the target graph. In practice, the smallest bounding box of the target graph may be displayed in the untagged document, so that the target graph can be highlighted. Thereby, the user can be enabled to quickly select the entire chart or image in the untagged document.

It should be noted that the first point-and-click operation, the second point-and-click operation, the third point-and-click operation, the fourth point-and-click operation, the fifth point-and-click operation, the sixth point-and-click operation, and the seventh point-and-click operation in the embodiments of the present disclosure are different point-and-click operations that can be distinguished by the clicking method and the area corresponding to the clicked position.

The foregoing embodiments of the present disclosure have the following beneficial effects: through the document content point-and-click method of some embodiments of the present disclosure, the user operation of selecting the document content in an untagged document is simplified, and the time for the user to select the document content in the untagged document is shortened. To be specific, the reason why the user's operation of selecting the document content in the untagged document is cumbersome and the time for the user to select the document content in the untagged document is rather long, lies in that: the user needs to accurately pull and select the document content required to be selected, and if the selected document content is incorrect, the user needs to do it again, which makes the user's operation rather cumbersome, and when pulls to the end of the document content to be selected, in order to accurately select the document content, the user needs to slow down the pull speed, which results in a fairly long time for pulling and selecting the document content. On this basis, the document content point-and-select method according to some embodiments of the present disclosure, in response to detecting a point-and-click operation acting on the untagged document, firstly determines the document location information of the point-and-click operation. Thus, the document location information can characterize the location where the user clicked in the untagged document. Then, a document structure recognition result of the document content at the document location characterized by the document location information in the untagged document is determined. Thus, the document structure recognition result of the document content corresponding to the location can be determined through the location clicked by the user in the untagged document. Thereafter, in response to determining that the point-and-click operation is a first point-and-click operation, select the word text corresponding to the document location information from the document structure recognition result as a target word, and highlight the area corresponding to the target word in the untagged document. Therefore, when the point-and-click operation is a first point-and-click operation, the word text corresponding to the clicked location is selected and highlighted from the document structure recognition result, thus showing the effect of having selected a word. Finally, in response to determining that the point-and-click operation is a second point-and-click operation, the sentence text corresponding to the document location information is selected from the document structure recognition result as a target sentence, and the area corresponding to the target sentence in the untagged document is highlighted. Therefore, when the point-and-click operation is a second point-and-click operation, it is possible to select and highlight the sentence text corresponding to the clicked location from the document structure recognition result, thus showing the effect of having selected a single sentence. Also because the user does not use the pull-and-select method when making selections, the content in the untagged document can be selected directly through a point-and-click operation, thus simplifying the user's operation of selecting the document content in the untagged document and shortening the time for the user to select the document content in the untagged document.
